The Indo-Aryan invasions into the Indian subcontinent may have occurred in multiple waves from Central Asia and may have happened around 1500 BCE. This period marks the end of the Indus Valley Civilization and the beginning of the Vedic Age.
The Indo-Aryans’ arrival in northern India is believed to have occurred between 2000 BCE and 1500 BCE. This is determined through linguistic, archaeological, and genetic data that indicate a gradual migration of people from Central Asia into South Asia after the end of the Indus Valley Civilization.
